Do long UTM codes hurt SEO?
- 
					
					
					
					
 Since most UTM codes/URLs are longer than 70ish characters, is this hurting my SEO? If it is, how can I solve the problem while still using a UTM code? Thanks!

 The correct way to use UTM tracking without hurting your SEO efforts is to make sure you’ve implemented your canonical tags correctly. You should add self-referring canonical tags, which will prevent multiple versions of the same page from being indexed. For example: should have a canonical tag that looks like this: If you have pages with these parameters on your site then you should use the rel=”canonical” tag to specify the canonical URL that you’d like Google to rank. I hope this information answers your question. if you consider that my answer is good enough don't forget to mark it as a Good Answer Regards and have a great day

		Craft CMS SEO Resources
 I'm just starting out in freelance SEO & I've taken on a client who is using Craft CMS (version 2.0ish) for their site. I am not even close to being competent enough to manually code via Twig, but I had the main developer install the SEOmatic plugin for me. My question from here is - are there any resources or tips I should be aware of starting out? I just started by updating meta title/descriptions via "New Template Meta(s)" but I'm a bit concerned i'm doing the "template path" thing right - I haven't seen any visible changes in browser, and the SERP preview I'm getting is giving me a broken link. But i'm doing a fresh Moz crawl right now to see if the changes took place or not. so 1. Am I on the right track? 2. How long does it typically take for changes to start to show? 3. Is there anything I should be aware of? any follow up questions just let me know, I'll be following this thread! Technical SEO | | dig_ad_austin0

		422 vs 404 Status Codes
 We work with an automotive industry platform provider and whenever a vehicle is removed from inventory, a 404 error is returned. Being that inventory moves so quickly, we have a host of 404 errors in search console. The fix that the platform provider proposed was to return a 422 status code vs a 404. I'm not familiar with how a 422 may impact our optimization efforts. Is this a good approach, since there is no scalable way to 301 redirect all of those dead inventory pages.

		Target: blank. Does it make an SEO difference?
 I've notice many sites MOZ included no longer use the target: blank attribute. I think that's what it's called. Basically when a link on your site opens a new tab in the browser as opposed to replacing the browser window you are in. Given that MOZ think of everything, I would love to hear opinions on this.

		SEO value of InDesign pages?
 Hi there, my company is exploring creating an online magazine built with Adobe's InDesign toolset. If we proceeded with this, could we make these pages "as spiderable" as normal html/css webpages? Or are we limited to them being less spiderable, or not at all spiderable? Technical SEO | | TheaterMania1

		How long should I keep 301 redirects?
 I have modified a the URL structure of a whole section of a website and used mod_rewrite 301 redirect to match the new structure. Now that was around 3 months ago and I was wondering how long should I keep this redirect for? As it is a new website I am quite sure that there are no links around with the old URL structure but still I can see the google bot trying from time to time to access the old URL structure. Shouldn't the google bot learn from this 301 redirect and not go anymore for the old URL? Technical SEO | | socialtowards0

		Does Bitly hurt your SEO?
 I often use bit.ly or Google URL shortener in links when other websites post my articles so I can track clicks. However, I am thinking this may HURT my SEO given that it is taking away a back link to my website. Is that logic correct ? If so, what is a good way to be able to track clicks if a website posts your article without jeopardizing the SEO value? Technical SEO | | StreetwiseReports1

		What are your best tips for SEO on a shopping cart?
 So, I am working on a shopping cart platform (X-Cart) and so far don't like it. Also, the web designer is not someone I've worked with before and he is understandably conservative about access--which limits what I can and cannot do from the back end. One of the things I like to do is include text for the search engines. However, based on conversion, etc., I think the product images on a landing page (main brand info with specific products that show up) should show up first to move toward conversion first. I am thinking of adding the text below the product images on the brand pages so the viewer sees the products first while still keeping the content seo. My practice is to use between 300-350 words minimum on a page. Just wondering what best practices you have for a shopping cart. Care to share? Any tips or hints? Thoughts on what I might do that would be most effective? As always, thanks in advance for your sage advice! Technical SEO | | TheARKlady0

		Putting nav code at the bottom of a page?
 Hey, We are doing a re-design on our websites and we have run into a little problem. Basically we need to put the nav code at the bottom of the page (so when you view source all the nav code it at the bottom) but the nav will of course still show at the top. Will this cause any issues with our SEO? Will it make the nav seem less important or get crawled less? Thanks for the help in advance!
